After installing the wave driver, ensure that the wave driver is only used by TAPI. Otherwise, the system starts using the wave driver inappropriately. For example, the system might start playing ding.wav when you receive an email. Use the following procedure after installing the wave driver on Windows XP and Windows 2000.
Procedure
From the Control Panel, select Sounds and Audio Devices.
Ensure that no preferred devices use the WIDWOD32 driver.
To prevent the drivers from been used explicitly:
Go to Sounds and Audio Devices > Hardware > Avaya IP400 32 bit WIDWOD Driver > Properties.
